"NITED STATES LEOPOLD BERGER, OF NEW PATENT OFFICE.

NEW YORK.

STATION-INDICATOR.

SPECIFICATION forming part of Letters Patent No. 392,304, dated November 6, 1888.

Application filed March 20, 1888. Serial No. 267,853. (No model.)

.To all whom it may concern.-

Be it known that we, LEOPOLD BERGER, of New York city, New York, and MARTIN FAAS, of Brooklyn, New York, have invented a new and Improved Station-Indicator, of which the following is a specification.

Our invention relates to the construction of an indicator for railway or other stations; and it consists of the various elements of improvement hereinafter fully described.

In the'accompanying drawings, Figure 1 is a front view of the indicator with part of the outer face-plate removed. Fig. 2 is a crosssection at line A A, Fig. 1, looking toward the right; and Fig. 3 is a cross-section at line BB, Fig. 1, looking towardthe left.

C O are two rollers or drums placed behind each other. The end of a band or ribbon, D, is fastened upon one of said drumssay C and the desired amount of ribbon wound upon said drumand then passes around fixed guiding-rods a b, then between the drums O. 0 around fixed guides d e, and then around a movable guiding-rod, f, to the other drum, 0, and its other end attached to said drum 0. (See Fig. 2.) By this arrangement the front of the ribbon or band D will come toward one side, X, of the box, while the back of said ribbon will come toward and be exposed at the other side, Y, of the box Z, containing the mechanism.

When the drums are operated by the rod E in the manner hereinafter described, the faces of the ribbon D, exposed at both sides of the box, will move in the direction of the arrows 8, and when the drums, and consequently the ribbons, are operated by the rod E, the faces of said ribbons will move in the opposite direction or in the direction of the arrows 9. The names of the different stations are printed or painted upon both sides of this ribbon D, but in a position and direction directly opposite to each other, and must be arranged in such a manner that the name of one and the same station appears at both sides of the box at one and the same time.

To regulate the difference in diameter of the rollers when the required amount of ribbon is wound upon one roller and unwound from the other, the guiding-rod f is made movable. This rod f is carried upon the end of levers g, turning freely on center h, fast to the frame F, and acted upon by springs 70 to force the guiding-rod f upward, and thus take up any slack of the ribbon, and at the same time regulate the motion of the same.

The rollers O O are connected together by gear-wheels mm, (shown in dotted lines in Fig. 3,) to communicate any motion given by one roller to the other. One of these rollers, O, is provided at its end with a disk, Gr, having projections t on its circumference similar to a ratchet-wheel, against which pawl-levers J J are made to work. These pawl-levers J J are hinged upon levers H H, respectively, turning freely upon a fixed center, 1). One of these pawls, J, acts against the upper side, and the other pawl against the lower side of the ratchet-disk G, for the purpose of turning,

the roller 0 either in one or the other direction.

To the levers H H the rods E E are connected, to operate the same. Springsn n, attached to the levers H H, move the same back again into their original position.

To one of the gear-wheels, m, a number of projecting pins, 1', are attached, corresponding in number with the number of projections i on the disk G. Levers s s are arranged and acted upon by these projecting pinsr-via, the lever s when the roller turns in one direction and the lever s when said roller is turned in the opposite direction. The levers s .9 act upon a spring-hammer, L, which by each operation strikes the bell M, thereby giving a sign or alarm whenever the name of station is changed.

In both sides XY of the box openings u are arranged, closed by a glass plate, 12, on the inside, through which the printed or painted name of the station can readily be seen, as shown in dotted lines in Fig. 2.

What we claim is- 1. The combination of rollers O C with the gear-wheels m m, and with ribbon D, and with a movable bar, f, and with lever 9, turningon center]: and enrryingsaid lmr, and \viLh r en whee] m, and with levers s 5', neted Upon the spring 7., acting on lever 1 substantially by these pins, and with spring-hmmner Land 10 as specified. bell M, substantially as specified. 2.
